Im selling my GFB, because I just recently installed a cone filter and the 2 don't seem to get along. Me and my friend installed it on his car and it worked fine. So I switched back to stock and the GFB is for sale. Asking $270 shipped, Im going to throw in the whistling trumpet for no additional cost. For those of you that don't know about this valve, it can be adjusted to vta as much as you like(therefore being louder)or recirc. as much as possible if you dont want the whoosh sound. If interested Email at evovegeta@yahoo.com or just PM me
